Using version ^7.30 for illuminate/redis
./composer.json has been updated
Running composer update illuminate/redis

Updating dependencies
Your requirements could not be resolved to an installable set of packages.
Problem 1
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require illuminate/redis:*" to figure out if any version is installable, or "composer require illuminate/redis:^2.1" if you know which you need.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
